General Commands Manual
NAME gcore — get core images of running process
[-c corename] pid [pid ...]
creates a core image of the specified processes suitable for use with gdb(1)
. By default, the core is written to the file “<progname>.core
”, where “<progname
>” is the program name of the process corresponding to the pid that is given on the command line. This filename can be changed by supplying the -c corename
argument, or setting “proc.<pid>.corename
” with sysctl(8)
The core image.
HISTORY gcore appeared in 4.2BSD, disappeared in NetBSD 1.2, and reappeared in NetBSD 2.0.
BUGS The process is not stopped while the core file is generated, so it might not be consistent.
